To (ZZZ 20 7mm it may concern:

Be it known that I, ARTHUR JOHN LEWIS EoKnRsLEY, a subject of the King or Great Britain, and resident of corner Haig and Clarendon streets, South Melbourne, in the State of Victoria, Commonwealth of Australia, have invented a certain new and use- :lul Appliance for Delivering Eilervescent Liquids, of which the following is a specification.

This invention has been devised in order to provide an appliance for delivering gaseous liquids and has combined therewith means for deliverin syrup or other liquids for the purpose of supplying or vending effervescent drinks.

The invention has been devised in order to provide a cheap, simple and eilicient appliance whereby mixed effervescent drinks such as soda water, and a syrup or syrups may be simultaneously vended or delivered as required.

An essential feature o1 the invention consists in the use of a loose valve controlling the supply of gaseous liquids, the lower por: tion of the valve being spring controlled and loose on the shank or stern, so permitting of furthenmovement of the shank after the valve is on its seat and to allow of the operation of the shift and syrup valves irrespective of the said loose valve controlling the flow of the gaseous liquid.

A further essential feature consists in the gland ring or joint for the loose valve stem.

In order that the invention may be more readily understood, it will now be described with reference to the accompanying drawings, in which- Figure 1 is a view in elevation of the improved appliance for delivering effervescent liquids.

Fig. 2 and Fig. 3 is a view in perspective of a detail. Fig. 4 is a view in vertical central section of a modification oi the device, and

is a view in plan of the invention,

The invention consists of a container 36 of tubular or other shape in cross section constructed of suitable material and formed with a top portion 37at its upper end havinga branch pipe 38 projecting at right angles thereto and'adapted to connect the supply of gaseous liquid, the supply pipe connecting the threaded end 89 thereof within the cover piece 32 which may be fitted to any suitable support.

The upper end 37 of the tubular container 36 is provided with a vertical tubular portion '41, a packing gland 5 held on its seat 8 by means of the threaded portion 42 and through which the'stein 26 of a valve 9 controlling the supply of gaseous liquid into the chamber 36 is adapted to slide.

This controlling valve 9 is provided with a seat 3 within the tubular portion 41 and is formed or" a tubular member 9 formed on its underside with a valve ring 10 within a recess 43 adapted to rest upon the seat 3* ,which is formed upon a downwardly projecting supply tube 16 threaded at 44 to the container top 37. I

The valve 9 is loose on the stem 26 which is formed with a flange held up by the spring 39 against the nut 44 threading upon the valve 9, the seat 10 of the valve 9 being held by the screw 44 extending from the underside thereof.

The valve 9 being loose on the shank or stem 26 allows of further movement of the said stem while the said valve is on its The valve stem 26 at its upper end passes through a gland 5 recessed at 46 and threads into or otherwise connects an extension 4 "formed with a hole 47 of sufiicient size to allow the arm 48 of the handle 1 to pass therethrough. The gland 5 is made airtight by a ring 49 having a washer 50 on its underside resting on the .Q'land seating and a further washer 52 on the top of the ring 49 upon which the gland nut 5 is adapted to bear the upper washer being formed with a tubular projection 53 within the hole of the ring 49. r

The supply tube 16 within the container is v formed with a rim or flange 42 While a packing ring 44 is provided between it and the underside of the top .37 the depending tube 16 pro ecting nearly to the bottom of the container 36.

A sleeve valve 17 is adapted to encircle the lower endof the said tube 16, so providing means whereby the liquid supply is efl'ectually cut off from the containerduring the delivery of the gaseous liquid therefrom.

This valve 17 is normally held open by a helical spring 19 arranged in a'recess 54 formed between the flanges 55, 56, of the sald sleeve valve 17 and the delivery orifice of the container respectively, the upward movement of the sleeve valve 17 being limited by the tube 16 within the container 36, the lower end of which is encircled by the tubular upper end 57 of the sleeve. valve.

. The upper and lower tubular members thegaseous liquid in passing through the delivered through the delivery orifice 66.

tubular extension 16 impinges on the disk 59 closes the valve against the seat and allows the liquid to be fed under pressure through perforations or openings 64 in the upper portion 57 of the valve 17, into the chamber 2.

The perforations 62 on the lower tubular member. of the'sleeve valve 17 are adapted to allow the liquid in the container 2 to be thereof into a receptacle placed ready to receive it.

A snift or exhaust valve 14 is arranged within the upper end of the container 2 and consists of a valve having tapering 0r conical surface within which is a valve seating 15 the upper surface of which bears against the underside of the valve seat 68 formed on a tube 13 fastened to the cap 37. The valve 14 is held to its stem 69 by a nut 7 0 as illustrated. The valve stem 69 projects vertically through the tube 13 which is recessed at 71 to receive a spring 12 which bears against the enlarged head 11 of the valve stem 69 and retains the snift valve normally up against its seat. A suitable exhaust orifice is formed within the sleeve or tube 13 and connects an exhaust pipe 70 arranged to project to anydesired position.

A controlling lever l is arranged vertically and at its lower end 2 is pivoted at 3 to a bracket 71 formed on the cap or top 37 being provided at its lower end with horizontal projections 48, 74, the projection 48 extending through a slot 47 formed in the upper end of the stem26 of the controlling valve 9 andalso rests upon the cap 11 carrying the stem 69 of the snift valve 14.

The projection 74 of the lever 1 is adapted to control the opening and closing of a valve or valves 28 of a syrupsupply or supplies so that if desired, a mixed effervescent drink consists of a disk may be vended; for instance, one, two or more syrups may be mlxed wlth soda water or other gaseous l1qu1d.

The valve mechanism for each syrup sup-' ply connects the container 36 by a bracket 70 or support 79. It is preferred, however, that the syrup valve compartments connect thebracket 16 while the end 74 of the lever lis adapted, to pivotally or rigidly connect the bracket or opening and closing of the valves thereof.

In the drawings, for the purpose of illus tration, two syrup devices are illustrated connected to the bridge .16' but it will be obvious that a convenient number may be adapted to be of any suitable len th capable of receiving and supporting any convenient number of syrup supply valve stems 31, the 7 ends of the stems above the bridge plate 16 being preferably formed with an enlarged head 22. Upon this bridge piece or plate 16 is a sliding member or plate 23 having formed with a tongue 11 working in a groove in the bridge piece 16 but it will be readily understood that the sliding joint may be of any other preferred construction.

When sets of two syrup valves 30 are fitted to thedispensers as illustrated in Fig. 2, the sliding plate 23 may be formed with a groove 17'at either end adapted to partially pass around the particular valve stem 31 below the head22 to enable the syrup valve 30 to be operated and in" this mannera connection is then made betweenthe bridge 16 and the enlarged head 22 of the stem 31 to allow. of the raising of the valve stem 31 which connects the particular syrup valve 30 and the syrup flows as required.

In the modification illustrated in Figs. 4 and 5 the sliding plate 23 is slotted along its length, the slot 18 being of sutficient width to allow of working clearance with the valve stems 31 of the system. The underside of the enlarged'head 22 of each of the valve stems 31 is adapted to loosely 120 engage the sliding plate 23*, the latter being arranged to slidethe whole length of the bridge 16 and is formed with an arch 21' extending from either side, the arch beingof suflicient size toclear the enlarged head 22 125 of each valve stem 31. The plate 23 at its lower edges is formed with angular faces 6 adapted to be held in grooves formed in the ridge 16".

It will be obvious that the sliding plate 130 bridge 16 connecting the 7 Y syrup supply devices and which controls the 23 upon the bridge 16 may be of any suitable length provided the arch 21 formed thereon is adapted to come to rest immediately around or over the enlarged head 22 of any particular valve stem 31 in the system to enable the plate 23 to pass between the head 22 and the bridge 16*, and with this construction any suitable number of valve stems 31 may connect the bridge 16.

By this means, when the handle 1 of the lever 2 controlling the effervescent liquid dispenser 36 is brought to position for operating any particular syrup supply valve 30, the arch 21 of the sliding plate 23 having already been brought to position over the particular syrup supply stem 31, that particular valve is opened and the syrup is supplied through its delivery pipe in the usual manner. 1

The syrup valve stems 31 are divided and the valves 30 are regulated by the nut 2 1 working on the thread of the stem 31 so that by the adjustment of the nut on the upper portion of the stem 31 the stroke of the valves 30 in the system is regulated, while the lower portion of the stem is fitted with a knuckle or other pivot joint 25 and the valve 30 acts against the compression of the spring 26.

Each of the stems 31. projects vertically and downwardly and is threaded into the lower portion of the valve stem being held by a nut 2d and is knuckle jointed at 25. The stem 31 engages a double cone valve 28, 3O fitted with a rubber or flexible disk 29 to make an effective joint and the stem 31 is also provided with a helical return spring 27 between the uppercone 28 and the top of the cap 26 of the valve chamber 78 preferably connecting by the bracket 79 with the container 36 of the gaseous liquid supply.

This valve chamber 78 communicates with the syrup supply under a sufiicient head or pressure by the pipe 31 and is provided with a delivery orifice 79 normally closed by the valve 28, 30 under the action of its controlling spring 27.

The adjusting nuts 24 may be adjusted so that according to the position, so will the flow of syrup or syrups be regulated while the supply of syrup can be readily cut out should the sliding member 23 be in the nor mal position out of contact with the head 22 of each valve stem 31.

It is preferred that such delivery pipe 7 9 leading from the syrup supply valve compartments 78 be bent and have their delivery orifices adjacent to the outlet 66 of the gaseous liquid supply to facilitate the mixing of the liquids and so deliver an effervescent liquid to the receiver in the one operation of the controlling lever. The appliance may be readily fitted by means of adjusting nut-s 35 to a counter or other support 80.

In order to limit the movements of the valve 9 snift valve 14: and syrup valves 30, the bracket 71 is provided with a stop surface 81 so limiting the movement of the lever or handle 1 in the one direction and prevents undue outward movement of the valve stem 26.

In the operation of filling the chamber with gaseous liquid, the snift valve is closed and the controlling valve lifted by means of the pivoted handle 1 working in one direction, the supply under pressure being delivered down through the tube 16 to the lower end of the container under pressure, impinging on and closing the lower or delivery sleeve valve 17 upon its seat, the chamber being thereby filled through the perforations 64: as required.

lVhen it is desired to empty or deliver liquid from the chamber 36 the controlling valve 9 is closed upon its seat by the return of the lever 1 to an approximately vertical position, thereby preventing the further supply of gaseous liquid to the chamber 36, while the spring 19 of the lower delivery sleeve valve 17 being freed from gas pressure, exerts an upward pressure, and, opens the lower valve 17 thus allowing the liquid to be delivered by gravitation through the hollow stem 58 to the orifice 66 and into the receptacle as required.

When it is desired to mix the gaseous liquid with a syrup or syrups, the sliding plate a 23 is brought to a position to partially pass around the particular valve stem 31 below the head 22. This operation allows the rod 31 on the snifting of the compartment 36 to open the supply valve 30 and to simultaneously deliver the syrup or syrups with the liquid in the container 36, on the snifting operation of the lever or handle 1, which operates in the reverse direction to the movement given thereto when opening the gaseous liquid supply valve 9. The loose movement of the valve stem 26 enables this operation to be accomplished without disturbing the valve 9 from its seat during the snifting operation.

It will therefore be obvious that the delivery of the liquid is controlled by a single operation of the handle 1 which action opens the snifting valve 14: which reduces the gas pressure in the container, opens the syrup valve or valves 30 and on the reduction of the pressure in the container 36, the sleeve valve 17 automatically opens by the action of its spring 19, and the liquid from the container 36 and syrup or syrups flow simultaneously by gravitation into the receiver.

Having now fully described and ascertained my said invention and the manner in which it is to be performed I declare that what I claim is 1. A11 appliance for delivering effervescent liquids consisting in the combination of a container having a top formed with a tubular extension communicating with a gaseous liquid supply, a spring controlled valve loose on its stem controlling the inlet orifice of a downwardly depending tube connecting the cap and projecting within the container, a spring controlled and perforated sleeve valve arranged around the lower end of said tube and adapted to allow the gaseous liquid from the pipe to pass into the container also to control the delivery from the container, a spring controlled snift valve arranged within the container, the stem thereof projecting vertically through a sleeve fitted to the cap of the container, a head or cap on saidstem and one or more syrup supply devices each consisting of a valve chamber, a spring controlled valve in said chamber, an inlet and delivery pipe to said chamber, a rod connecting the valve with a pivoted adjusting lever adapted to engage a slidable member carried by a bridge or cross piece connecting a controlling lever or handle pivoted to a bracket connected to the inlet pipe of the appliance, the said handle being formed with a lever also adapted to pass through a the stem of the gaseous liquid supply valve and also bearing upon the stem of the snift valve, the whole being arranged and operating in such a manner that when the supply valve within the container is opened, the gaseous pressure of the liquid closes the sleeve delivery valve and the container is filled, the handle being then returned to or past the normal ply valve to its seat while on the further operation of the handle, the snift valve is position returning the sup- 7 opened releasing the gas, pressure in the container, so causing the sleeve delivery valve to automatically open and at the same time, the syrup supply is opened, the inlet valve within the container during this operation remaining closed until the next operation of the handle for filling the container, substantially as described and illustrated.

2. In an appliance for delivering eiferves cent liquids, the combination of a gaseous liquid feed pipe; a receptacle communicating with said feed pipe, there being a chamber between the feed pipe and the receptacle and a port between said chamber and said receptacle; a valve located in said chamber, said valve being adapted to seat upon said port to prevent the feed of gaseous liquid to the receptacle; a valve stem connected to said valve and having a limited movement independently of said valve; a spring between the stem and the valve whereby the valve is moved on the initial movement of the stem to seat upon the port; a lever connected to the valve stem to operate the same; and an exhaust valve for the receptacle, said exhaust valve being operable by said lever whenthe latter is operated to close the port leading to the receptacle and after the first-named valve is seated, said spring permitting the continued movement of the lever and valve stem during the operation of the exhaust valve.
